Create Rice Krispies In Chocolate
You could accomplish this with a shader. The acitve ingredient is the Noise Texture connected through the height input of a Bump Node.  I added the Diaplacement for added effect, but it is optional (especially in eevee). The rest, I just used as an example of how the whole thing can be made through a shader (not just the crispy bits), should you choose to do so.

With a just a bit more complexity to the graph in the form of removing the Z input vector on the Noise Texture, you can achieve a melted, or cut look on the sides, and another noise texture (clamped with a ColorRamp) adds some more &quot;rice bits&quot; showing through. I also combined the &quot;rice bits&quot; to make a roughness texture so they don't shine like the &quot;chocolate&quot;. The more complex you make the graph, the closer to real you can get.
